<div>A seastead is a structure which is safe to live on in international waters. The goal is to enable [[dynamic geography]] where people can pick which legal system they are in without having to box up their stuff and change houses. Since the focus is on living on the water, not getting anywhere quickly or carrying heavy cargo, a seastead design can sacrifice speed through the water and cargo capacity to achieve lower costs per square foot and greater stability than a boat/yacht/ship of similar price. The goal of seasteading is to make a community of people living on seasteads.<br />
<br />
There are several different lines of thinking about what seasteads should look like and the best strategies to get them built. The table below shows the main visions for what we should be working on to advance seasteading.<br />

<div>== Concrete Shell Seasteading ==<br />
<br />
<br />
concrete shell seasteading is seasteading based on concrete shells like spheres, lenses, and blimp shapes. <br />
<br />
It differenciates from concrete floats like used in houseboat building by the curved nature of the shapes that gives a lot more structural integrity and makes the float "open water capeable" <br />
<br />
Houses on concrete rafts have been in use for quite a time now - but they are limited to very protected water spaces. On contrary a concrete shell wraped around your living space gives it a absolute new class of open water capeability.<br />
<br />
Similar concepts have been discussed at:<br />
<br />
http://wiki.seasteading.org/index.php/User:Vincecate/BallHouse<br />
<br />
http://wiki.seasteading.org/index.php/User:Vincecate/GeodesicVessel<br />
<br />
http://wiki.seasteading.org/index.php/User:Vincecate/WaterWalker<br />
<br />
http://wiki.seasteading.org/index.php/User:Jesrad/BunkerStead<br />
<br />
<br />
What differs "concrete shell seasteading" most from the other concepts is that the shell is not a auxiliary part that supports a kind of light platform but it is the seastead in itself. <br />
<br />
It is also of essence that the shell is built in reinforced concrete not in steel, not in ferrocement, not in other materials as only reinforced concrete structures offer a maintenance free service life of 200 years in marine ambient.<br />
<br />
shell seasteading is not living in a bunker! on contrary it can be very close to living on a luxury yacht - just MUCH more affordable - literally at average US and European housing prices instead of "yacht prices".<br />
<br />
For a good impression how concrete shell seasteading would look like check this artist vision [http://imulead.com/tolimared/concretesubmarine/marine/image/lens.htm floating lens island]<br />
<br />
:http://imulead.com/tolimared/concretesubmarine/marine/image/lens.jpg<br />
<br />
In a future city seastead each family house seastead would form part of the city just like the plastic bottle island is based on small bouyant units tied together. Hundreds of concrete shell structures would form a settlement that is unsinkable and redundant similar to the plastic bottle island.<br />

<div>Concrete shell building has 2 main fields<br />
<br />
A) '''Ferrocement Boat Building''' (Mesh wire based method)<br />
<br />
B) '''Structural Concrete Building''' (Cast method used in civil engineering)<br />
<br />
Both Methods has been used to create floating structures. Ferrocement is used in boatbuilding while structural concrete building is used for industrial floating structures like oil and gas platforms.<br />
<br />
Especially concrete cast structures like '''Troll A''' and the '''Nkossa Barge''' have been acnowledged to have a maintenance free service life of 200 years in marine environment what makes them a top option for the purpose of seasteading. Drawback of concrete cast structures is that the shell thickness has to be some 10cm as a minimum - the structures will be too heavy for normal "boating purpose" so the method was never used on a large scale in boat building but opens great possibilities for hulls where light is not a design goal - this is industry, seasteading, and submarine applications.<br />
<br />
Mesh wire based Ferrocement structures on the other hand can be performed in much thinner layers and has achieved certain popularity in yacht building - the drawback is that the service life depends strongly on the building quality and is less favorable than for concrete cast structures.<br />
<br />
One of the seastead designs based on concrete cast structures is the [http://seasteading.org/interact/forums/engineering/structure-designs/the-seastar-platform Seastar Platform]<br />
<br />
Seastar Platforms bring the benefit of industrial floating concrete structures to Single Family Seastead building.Among those are mantenance free operation, low cost per squaremeter of living space(compareable to US and European housing prices). They are scaleable, repairable, and can form part of a "seastar grid comunity".<br />

:"...Foamed concrete or lightweight concrete derived from Allied's aqueous foams are suitable for both precast and cast-in-place applications. Some of the highly insulative cementitious foams at densities 48 kg/m3(3 pcf) to 645 kg/m3(40 pcf) or higher can be used as block fills, lightweight roof deck and void-fill materials. Good strength characteristics with reduced weight make lightweight concrete based on Allied's aqueous foams suitable for structural and semi-structural applications such as lightweight partitions, wall and floor panels, and lightweight blocks. Cementitious foams derived from Allied's premium systems are suitable for thin layer coating applications where specific performance criteria are required.<br />
<br />
:Foamed concrete and foamed cement made with Allied's foam have very fine pore structure, unlike that made with conventional proteinaceous and surfactant foams. The pore structure of Allied's foams hardly show any sign of deterioration as the density of the foamed cement decreases to below 160 kg/m3 (10 pcf). At densities below 160 kg/m3, the pore texture of foamed cement derived from conventional foam agents becomes so coarse that most of them show severe structural collapse...."<br />

:Geopolymers are a type of inorganic polymer formed at room temperature by using industrial waste or by-products as source materials to form a solid binder that looks like and performs a similar function to ordinary Portland cement. Geopolymer binder can be used in applications to replace or partially replace ordinary Portland cement with environmental and technical benefits, including an 80-90% reduction in CO2 emissions and improved resistance to fire and aggressive chemicals. Find further details of the environmental benefits of geopolymer technology in our environment section.<br />

:"...Foamed concrete or lightweight concrete derived from Allied's aqueous foams are suitable for both precast and cast-in-place applications. Some of the highly insulative cementitious foams at densities 48 kg/m3(3 pcf) to 645 kg/m3(40 pcf) or higher can be used as block fills, lightweight roof deck and void-fill materials. Good strength characteristics with reduced weight make lightweight concrete based on Allied's aqueous foams suitable for structural and semi-structural applications such as lightweight partitions, wall and floor panels, and lightweight blocks. Cementitious foams derived from Allied's premium systems are suitable for thin layer coating applications where specific performance criteria are required.<br />
<br />
:Foamed concrete and foamed cement made with Allied's foam have very fine pore structure, unlike that made with conventional proteinaceous and surfactant foams. The pore structure of Allied's foams hardly show any sign of deterioration as the density of the foamed cement decreases to below 160 kg/m3 (10 pcf). At densities below 160 kg/m3, the pore texture of foamed cement derived from conventional foam agents becomes so coarse that most of them show severe structural collapse...."<br />

:"...Zeobond Pty. Ltd. is a privately owned Australian-based company focused on the development, commercialisation and manufacturing of geopolymer technology.<br />
<br />
:Geopolymers are a type of inorganic polymer formed at room temperature by using industrial waste or by-products as source materials to form a solid binder that looks like and performs a similar function to ordinary Portland cement. Geopolymer binder can be used in applications to replace or partially replace ordinary Portland cement with environmental and technical benefits, including an 80-90% reduction in CO2 emissions and improved resistance to fire and aggressive chemicals. Find further details of the environmental benefits of geopolymer technology in our environment section.<br />

<div>== Concrete Shell Seasteading ==<br />
<br />
<br />
concrete shell seasteading is seasteading based on concrete shells like spheres, lenses, and blimp shapes. <br />
<br />
It differenciates from concrete floats like used in houseboat building by the curved nature of the shapes that gives a lot more structural integrity and makes the float "open water capeable" <br />
<br />
Houses on concrete rafts have been in use for quite a time now - but they are limited to very protected water spaces. On contrary a concrete shell wraped around your living space gives it a absolute new class of open water capeability.<br />

<br />
http://wiki.seasteading.org/index.php/User:Jesrad/BunkerStead<br />
<br />
<br />
What differs "concrete shell seasteading" most from the other concepts is that the shell is not a auxiliary part that supports a kind of light platform but it is the seastead in itself. <br />
<br />
It is also of essence that the shell is built in reinforced concrete not in steel, not in ferrocement, not in other materials as only reinforced concrete structures offer a maintenance free service life of 200 years in marine ambient.<br />
<br />
shell seasteading is not living in a bunker! on contrary it can be very close to living on a luxury yacht - just MUCH more affordable - literally at average US and European housing prices instead of "yacht prices".<br />

<div>Concrete Shell Seasteading<br />
<br />
concrete shell seasteading is seasteading based on concrete shells like spheres, lenses, and blimp shapes. <br />
<br />
It differenciates from concrete floats like used in houseboat building by the curved nature of the shapes that gives a lot more structural integrity and makes the float "open water capeable" <br />
<br />
Houses on concrete rafts have been in use for quite a time now - but they are limited to very protected water spaces. On contrary a concrete shell wraped around your living space gives it a absolute new class of open water capeability.<br />
<br />
Similar concepts have been discussed at:<br />

<br />
<br />
What differs "concrete shell seasteading" most from the other concepts is that the shell is not a auxiliary part that supports a kind of light platform but it is the seastead in itself. <br />
<br />
It is also of essence that the shell is built in reinforced concrete not in steel, not in ferrocement, not in other materials as only reinforced concrete structures offer a maintenance free service life of 200 years in marine ambient.<br />
<br />
shell seasteading is not living in a bunker! on contrary it can be very close to living on a luxury yacht - just MUCH more affordable - literally at average US and European housing prices instead of "yacht prices".<br />
<br />
